Abstract

A backward fluorescence collection method is employed in a noncollinear optical parametric amplification-gated femtosecond time-resolved fluorescence spectrometer to determine the detection limit of this recently developed technique. In this way the supercontinuum generation that interferes with the determination of the detection limit is completely excluded, and the achieved upper limit of the detectable photon number with the 150 fs gating pulse is approximately 19.
